Answer:
c) could be mistaken for food by some species, working their way up the food chain
Explanation:
Microbeads seem to take the appearance of fish eggs, of which some aquatic organisms usually feeds on these fish eggs on a normal day. So, these microbeads could be mistaken to be food source by some species, thereby ingesting these microbeads which could be a source of problem to their system and could district the ecosystem of such habitat. Hence, this poses a serious environmental concern for aquatic biologists.
Answer:
(E) Soil disturbances can result in fewer blooms, and hence lower seed production.
Explanation:
According to the experiment, the eight control plots were left undisturbed, that is, their soil was not exposed to any disturbance. On the other hand, the soil of the experimental plots was disturbed during the removal of dandelion species. This disturbance might have resulted in reduced flowering in the experimental plots due to many reasons such as removal of fertile topsoil.
The reduced flowering in these plots might have caused lower seed set. The control groups had undisturbed soil which in turn favored more flowering and seed production than in the experimental groups.
Definitely true, because it is in a constricted space and you end up breathing more of it in, causing more harmful effects than if you were smoking the cigarette yourself
Answer: due to insufficient exocytosis in the type II alveolar cells
Foods that contain more than one type of molecule help us meet our daily requirement of nutrients. There is a limit to how much we can eat in a day, so if nutrient rich foods are consumed, we can easily provide the necessary building blocks for our bodies to maintain healthy function. This is not possible with foods that contain only one type of molecule.
